[time-nuts] Fluke 6681/Pendulum CNT-81 arrival

[Magnus Danielson]

Hi!

Today my Fluke 6681/Pendulum CNT-81 arrived, one of the ones that showed up on
Ebay from Singapore a few weeks back. The calibration is still valid (but then,
the internal memory of it was lost and no paper, ah well, like I really cared).

It powered up nicely except for the comment that it lost the calibration
memory, but that can be handled.
It was a bit dirty, but some warm water and a cloth should handle that.

No problem operating it.

With 25 ps single-shot resolution it should be a nice counter for TI exercises.
Wasting the CNT-90 on static measurements isn't that fun, and the CNT-81 isn't
as noisy and powerhungry as the 5370B, which is a good thing most of the time.

Hmm, I should make a counter test soon. Just awaiting the next counter... :-P

Cheers,
Magnus
